SAP EAI have above things. Thanks Google :) In this post, I introduce how to refresh SAP RFC structure on Oracle SOA. Before I introduce that..Oracle must give main solutions !! Shortly, you can refer as following as steps.. Step 1. Open the sapjco3.jar file. (I used Jd-gui) Step 2. Open JCoRepository.class in the jar file. Step 3-1. (Refresh SAP RFC function) Use  removeFunctionTemplateFromCache and then, Use  getFunctionTemplate Step 3-2.

<Environment> ■ SOA Version : Oracle Cloud SOACS 12.2.1.4 (Market Place) ■ java version 1.8.0_261 ■ Java Memory Garbage Collection Type : G1GC ----------------------------------------------------------------------------------------------------- In this post, I will compare between  Parallel  GC and G1 GC for Oracle SOA(EAI). For this, you need to know something as bellow.. EAI - Enterprise Architecture Integration What is Java Memory Garbage Collection (GC)? - Memory management - Delete unused memory automatically Java Memory Garbage Collection Types - Serial Garbage Collector - Parallel Garbage Collector -> Default GC below 1.9 - CMS Garbage Collector - G1(Garbage First) Garbage Collector -> Default GC above 1.9 GC types - Minor and Major GC During GC - Stop the World : A ll application threads are stopped ----------------------------------------------------------------------------------------------------- Let's start!! Parallel   Garbage Collector Logic Shortly, Memor
